Stamp holder for embossing dies



Oct. 13, 1953 H. c. RICKENBACH STAMP HOLDER FOR EMBOSSING DIES FiledJuly '7, 1950 UUUUUUUC U INVENTOR. WC, My 71 Patented Oct. 13, 1953UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to holders for marking stamps of the type whichare struck a blow at the top, and it is among the objects thereof toprovide a holder adapted to receive a multiple 'of marking stamps whichshall provide positive vertical alignment of the stamps, preventwobbling thereof at the center, and be of relatively light weight whichis essential in holders carrying a large number of stamps for markingproducts in steel plants and the like.

It is a further object of the invention to provide a holder for stampingdies having spring means for holding the stamps in the holder and inwhich the springs are connected by a wire to prevent their becomingloose.

It is a further object of the invention to provide such a holder ofaluminum with a solid steel handle which prevents breakage in use.

It is still a further object of the invention to provide a die holder inwhich the main body portion is of rolled bar aluminum and is providedwith a top plate of steel for receiving glancing hammer blows, thecomposite structure being of relatively light weight compared to priorart holders made of all steel.

The invention will become more apparent from a consideration of theaccompanying drawing, constituting a part hereof, in which likereference characters designate like parts, and in which:

Fig. 1 is a side elevational view of a holder embodying the principlesof this invention;

Fig. 2 a top plan view thereof with the handle portion partially cutaway and with the cover plate removed;

Fig. 3 a vertical cross-sectional view of the holder shown in Fig. 1;

Fig. 4 a transverse section taken along the line 44, Fig. 2; and

Fig. 5 a front elevation of a fragmentary portion of a composite dieholder showing a modified form of attaching the cover plate to the bodyof the holder.

With reference to the several figures of the drawing, numeral ldesignates the die holder body made of rolled bar aluminum and havingrectangular openings 2 for receiving the stamping dies 3 which are ofsimilar shape, the openings 2 being larger than the bodies of the stamps3 to eliminate binding. A longitudinal slot 4 is provided adjacent therectangular openings 2, as shown in Fig. 2, and the body of the dieextends in one direction to provide an enlarged area for a rectangularopening 5 that receives a larger stamping die such as the stamp 6 ofFig. 1.

A steel handle 1 is attached to the holder 'l' by placing it through avertical opening 8 and fastening it by a rivet or screw 9 extendingthrough the body I and through the steel handle as shown in dotted linesin Fig. 2.

Disposed within the rectangular openings 2 of the holder I are fiatsprings I0, more clearly shown in Fig. 4 of the drawing, having eyeletsI! for receiving a wire or rod 12 that extends through all of theeyelets and into portions of slot 4 that extend beyond the opening 2 asshown in Fig. 2. In this manner the springs are simultaneously assembledby dropping them into the slot 4 of the block or holder I. A retainingcover of steel, designated by the numeral I4, is placed upon the holderI to retain the springs and wire and is secured thereto by screws 1 5 inthe manner shown in Fig. 1, or the cover may have an overlapping flangeI6, Fig. 5, for receiving screws I! at the side instead of the top ofthe cover It.

The cover piece I 4 is provided with rectangular openings [8 of asmaller area than the openings 2 of the aluminum block I. This is moreclearly shown in Fig. 4. of the drawings. Openings I 8 are of a size toprovide clearance for the stamps 3 which have a loose sliding fit in theopenings [8 and ample clearance in the opening 2 of the block I toprevent binding. The cover piece I 4 is of a sufiicient thickness toprovide enough depth area for the stamps 3 to maintain proper alignmentof the rows of stamps. The opening in the cover piece for the largestamp 6 is smaller than the opening 5, Fig. 2, to receive the stamp 6and maintain its alignment. The springs l0 provide sufficient grip toretain the stamps in the stamp block for handling purposes.

As shown in Figs. 1 and 3, feet H! are provided on which the block Irests when in use. These feet may be square headed screws placed intapped holes of the block I, as is clearly shown in the drawing. Thescrews are adjusted to the distance the ends of the dies should protrudebelow the die holder to provide proper working clearance to assurecontact of the face of the die with the work before the impact blow isapplied at the top of the die.

By the use of the composite aluminum and steel stamp holder, a lightweight, durable holder is provided by which a multiple of stamps can beused with facility. Also by utilizing a steel handle member I,sufiicient strength is provided to avoid fatigue and breakage of thehandle at the joint. It must be remembered that these die holders aresubjected to glancing blows when in use, which may include blows on thehandle portion 7. The die holder with the charge of dies is placed on asurface to be stamped, such as steel tubes or other steel products, andeach stamp is individually struck by a hammer blow to impart a series oflegends on the stamped article.

Although one embodiment of the invention has been herein illustrated anddescribed, it will be evident to those skilled in the art that variousmodifications may be made in the details of construction withoutdeparting from the principles herein set forth.

I claim:

1. A stamp holder having a body portion with a plurality oflongitudinally spaced rectangular openings and having a cover plate withopenings in register with the openings of the holder, said holder andplate being adapted to receive stamps with their axes in verticalalignment, said holder having leaf springs extending a substantialdistance into the rectangular openings for grippingly engaging the bodyof the stamps, said springs having eyelets at one end and a rodextending through said eyelets whereby they can be simultaneouslyinserted in the stamp holder between the body of the holder and thecover plate.

2. In a stamp holder, 2. base having a plurality of rectangular shapedslots extending vertically from the bottom of the holder and beingarranged in spaced relation axially of said holder, said holder having ashoulder on one side at the top of the rectangular slots, leaf springshaving eyelets and a rod which is disposed in the shoulder portions ofthe holder extending through said eyelets whereby said springs can besimultaneously inserted in the rectangular shaped slots, the body of thesprings extending downwardly against one wall of the rectangular slots,and a cover plate for said holder for retaining said springs and rodhaving rectangular openings in register with the openings of the basefor receiving stamping dies, the openings of the cover being of asmaller dimension than the slotted openings of the base to maintainworking alignment of the stamp dies relative to each other and in saidholder.
